Abstract (en)
[origin: WO2012140412A1] A method of making an upwardly open container having a base wall, an upright perimeter wall, and an upright internal wall between one part of the perimeter wall and another part of the perimeter wall, the perimeter wall and the internal wall forming first and second compartments within the container, wherein the method comprises injecting a molten water-soluble polymer into a mould cavity between cooperating male and female mould parts; wherein there are independently movable first and second male parts separated by a gap in which the internal wall is formed, and wherein the first and second male parts correspond to the first and second compartments of the container to be formed.
